JAR-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 752,024, dated.February 16, 1904. Application filed May'fi, 1903. Serial No. 155,771.(No model.)

To all whom it may concern.-

Be it known that I, HENRY S. Bnnwrne'ron, a citizen of the UnitedStates, residing at Baltimore city, in the State of Maryland, haveinvented certain new and useful Improvements in Jar-Closures, of whichthe following is a specification.

My invention relates to jar-closures; and the primary object of the sameis to provide a jar and a closure so constructed as to insure a closeand air-tight sealing of the jar by the mere forcing of the closure overthe mouth of the jar.

A further object of my invention is to combine with the jar and closurea suitable gasket, flat or round-preferably flatwhich will serve thedouble purpose of a fastening means for the closure to the jar and atthe same time perform the function of an air-tight packing therefor.

The invention consists of a jar formed adjacent to its mouth with anexternal annular shoulder and an external annular peripheral beadforming a recess above the bead and between the shoulder, whereby thepacking-gasket is retained in combination with a closure or cover havingan interior annular recess in the depending flange of the said closureor cover. A suitable packing-gasket is adapted to spread or rolldownward around the rounded peripheral bead on the jar and into therecess of the closure or cover, whence forced downward, making a perfectsealing contact, as well as performing the function of holding theclosure or cover firmly to the top of the jar. As the gasket spreads orrolls around the head on the jar it is forced into the recess in thedepending flange of the closure or cover, whereby the bead on the jarspreads or rolls the gasket into the recess of the closure or cover. (InPatent No. 715,345, issued to me on the 9th of December, 1902, theconstruction differs, as shown, in that the cover goes inside the mouthof the jar, whereas this application refers to a cover or closure beingplaced on the outside of a jar.)

The construction of the improvements are more fully hereinafterdescribed, in connection with the accompanying drawings, which form apart of this specification, and the novel features will be moreparticularly pointed out in the appended claims.

In Figure 1, the drawing is a View, partly vertical section and partlyin elevation, of a jar and closure. Fig. 2 is aflat gasket. Fig. 3 is around gasket.

In the drawings Fig. 1 shows a part section, the other part the outsideview of a preserving jar or bottle. a is the body of the jar, which hasan open neck provided with an external annular peripheral bead b, with acone projection on the top of it forming an external annular shoulder gand a recess 0. cl is the closure or cover, which is large enough on theinside to pass over the two projections, as shown, and is provided nearits lower edge with an annular recess 6, which receives and clamps thepacking f over the bead b. The packing f can be either fiat or round, asshown in Figs; 2 and 3 in part, and in place in Fig. 1.

Having describedmy invention, what I desire to secure by Letters Patentand claim is- 1. The combination with a jar formed on its upper edgewith an external annular shoulder and a rounded peripheral bead forminga recess between the shoulder and the head, of a closure comprisinga'cover having an annular recess placed within the depending flange ofsame, and an elastic gasket surrounding the annular bead on the jar andspread within the recess of the closure substantially as hereinbeforedescribed.

2. The combination with a jar formed with an external annular peripheralbead and an annular shoulder forming a recess. between said shoulder andbead, in which recess the gasket is laid, said recess having a roundedsurface in the formation of the bead on the jar, of a closure or coverhaving an annular recess Within its depending flange and an elasticgasket spread downward on the bead on the jar and in the recess in theclosure or cover whereby the gasket holds the cover firmly on the jarand acts as an air-tight packing substantially as hereinbeforedescribed.

In testimony whereof I have signed my name to this specification 1npresence of two Witnesses.
